| Compound | Description |
|---|
| Progesterone | The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS. |
| Cholesterol | The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. |
| desoxycorticosterone | A steroid metabolite that is the 11-deoxy derivative of CORTICOSTERONE and the 21-hydroxy derivative of PROGESTERONE |
| pregnenolone | A 21-carbon steroid, derived from CHOLESTEROL and found in steroid hormone-producing tissues. Pregnenolone is the precursor to GONADAL STEROID HORMONES and the adrenal CORTICOSTEROIDS. |
| cortodoxone | 17,21-Dihydroxypregn-4-ene-3,20-dione. A 17-hydroxycorticosteroid with glucocorticoid and anti-inflammatory activities. |
| 17-alpha-hydroxyprogesterone | A metabolite of PROGESTERONE with a hydroxyl group at the 17-alpha position. It serves as an intermediate in the biosynthesis of HYDROCORTISONE and GONADAL STEROID HORMONES. |
| 20,22-dihydroxycholesterol | RN given refers to (3beta,22R)-isomer |
| 20-alpha-dihydroprogesterone | A biologically active 20-alpha-reduced metabolite of PROGESTERONE. It is converted from progesterone to 20-alpha-hydroxypregn-4-en-3-one by the 20-ALPHA-HYDROXYSTEROID DEHYDROGENASE in the CORPUS LUTEUM and the PLACENTA. |
| (22r)-22-hydroxycholesterol | |
| pregnanolone | A pregnane found in the urine of pregnant women and sows. It has anesthetic, hypnotic, and sedative properties. |
| 17-alpha-hydroxypregnenolone | A 21-carbon steroid that is converted from PREGNENOLONE by STEROID 17-ALPHA-HYDROXYLASE. It is an intermediate in the delta-5 pathway of biosynthesis of GONADAL STEROID HORMONES and the adrenal CORTICOSTEROIDS. |
| 5-alpha-dihydroprogesterone | A biologically active 5-alpha-reduced metabolite of plasma PROGESTERONE. It is the immediate precursor of 5-alpha-pregnan-3-alpha-ol-20-one (ALLOPREGNANOLONE), a neuroactive steroid that binds with GABA(A) RECEPTOR. |
| 5-pregnene-3,20-diol | RN given refers to (3 beta,20 alpha)-isomer |
